Looking for an affordable alternative to gunning or casting? Try pumpable and shotcreting installation methods with the newly developed castable series of Höganäs Borgestad!
With over 200 years of refractory expertise, Höganäs Borgestad has been constantly researching and developing refractory materials to fulfil your current and future needs. Our latest additions to our product portfolio are the new SiC based pump and shotcrete materials.
The Right Refractory Material Selection
Although the choice of refractory materials is highly dependent on fuels, raw materials and operating conditions, consideration should be given to refractory materials that provide the highest thermal conductivity resistance and have the longest life. Höganäs Borgestad has developed pumpable and shot-cretable castables for you.
A shotcrete, or a wet mix, refractory is applied through an air pressure system after it has already been mixed with water. Using a paddle mixer, the shotcrete refractory is mixed with water until the desired consistency is present. The wet mix is then pumped through a double piston pump to the nozzle of the application gun. There, it is injected with compressed air and applied to the desired location e.g. the inside of a boiler.
Advantages of our new SiC based pump and shotcrete materials
- Flexibility – can move behind forms and around anchors in difficult to reach areas.
- Easy transportation of pumpable castables to high elevations, up to 100 meters height.
- High alkali & abrasion resistance – Silicon Carbide (SiC) refractories are protected from corrosion by alkalies. Alkali build up formation is drastically reduced and lifetime is extended.
- Quick installation through pumpable and shotcreting method.
Features & Application areas
HÖGANÄS PUMP LC S85 is a pumpable and shot-cretable low cement castable based on Silicon Carbide (SiC), with excellent physical and mechanical properties. This product has been specially designed for applications requiring very high thermal conductivity and alkali & abrasion resistance, such as power generation industries, waste incinerators and cement. It is recommended for use in combustion areas, cyclone burner, and any other application where these properties are necessary.
HÖGANÄS PUMP LC S70 is a pumpable low cement castable based on Silicon Carbide (SiC), with excellent physical and mechanical properties coupled with superior thermal conductivity. This product has been specially designed for applications demanding high thermal conductivity, abrasion, alkali and thermal shock resistance.
